Q: How do I confirm the JS80RT eagle-beak shear matches my 6-9 ton excavator?
A: JISAN maintains a full hydraulic and linkage database for Sany, XCMG, CAT, Komatsu, Kubota, and all mainstream compact brands. Our engineers match the JS80RT excavator scrap shear to your exact 6-9 ton carrier, calibrating the 200 bar working pressure, 100 L/min flow rate, and pin distance to prevent host overheating. Any failure caused by operation beyond rated tonnage will not be covered by warranty.
Q: What advantage does the differential acceleration valve bring to urban demolition work?
A: Compact carriers often have limited hydraulic flow (around 100 L/min). The JS80RT eagle-beak shear features a patented differential acceleration valve that increases no-load stroke speed by nearly 50%, reducing cycle time significantly. This compact demolition shear boosts daily output by over 30% in tight urban spaces without increasing fuel or labor costs, maximizing your ROI on this entry-level investment.
Q: What materials are used in the JS80RT, and is it durable enough for daily work?
A: The shell and upper bracket of the JS80RT adopt genuine SSAB Hardox450 wear-resistant steel, offering excellent rigidity and resistance to chipping and deformation. The cutting edges are made of high-hardness alloy steel. As a premium excavator shear attachment weighing only 580kg, it resists severe impact from rebar and structural steel while protecting your 6-9 ton carrier's boom from excessive load.
Q: What after-sales support does JISAN provide for this entry-level shear?
A: JISAN offers a global unified 10-30-824 rapid service: 10-minute customer reply, 30-minute technical plan, spare parts dispatched within 8 hours.
12-month warranty: shell, upper bracket, slewing bearing, hydraulic motor, cylinders, speed-up valve
6-month warranty: dual valve, pinion gear, gear cover
3-month warranty: solenoid valve, handle & foot switch, pivot pins
1-month warranty: alloy steel blades (breakage & peeling covered; wear & edge curling excluded)
Consumables (bolts, bearings, grease, fuses) are not covered. Every unit passes 48 lab tests before shipment, ensuring your scrap shear for excavator arrives ready to work.
Q: How does the JS80RT compare to a mini concrete crusher for indoor demolition?
A: If your primary target is exposed rebar, steel pipes, H-beams, and structural steel, the JS80RT eagle-beak shear is the ideal tool. A mini concrete crusher is designed strictly for crushing concrete blocks. Using a crusher on pure steel will destroy the jaws. Our 360° rotating eagle-beak design slices through metal cleanly and precisely, making it far more efficient for steel-focused demolition tasks in confined spaces.
Q: What is the service life of the blades, and are replacement parts readily available?
A: The double-sided alloy steel blades on this scrap metal shear can be flipped and reused for 3,000–5,000 hours under normal scrap work. A 1-month warranty covers breakage and chunk peeling. Uniform wear and edge curling are normal consumable loss. Bulk replacement excavator shear parts are always in stock for quick global shipping.
Q: What sets JISAN apart from cheap mini shear alternatives on the market?
A: Cheap entry-level shears often use weak domestic carbon steel that bends at the pivot points within weeks. As a direct china excavator shear factory, JISAN uses integrated Hardox450 steel and one-piece forged alloy pivot pins, guaranteeing the JS80RT will not deform under the 200 bar maximum pressure of a 6-9 ton carrier. Best value means premium materials at an accessible price point.
Q: What is the warranty policy for the Hardox450 shell plates?
A: Free component replacement is provided for original structural cracks within 12 months on the shear head for excavator. If a weld crack occurs within 6 months, we reimburse 200 RMB for local welding costs. Welding guidance is offered, with all freight borne by the buyer. Cracks caused by using the shear as a hammer, pry bar, or cutting beyond rated capacity are excluded.
Q: Can the JS80RT cut concrete? Should I use a small concrete crusher instead?
A: Only exposed rebar can be cut. Solid concrete and rock are strictly prohibited to avoid edge chipping and blade damage. If you need to process thick concrete walls or slabs, a small concrete crusher is the appropriate tool. The JS80RT is engineered exclusively as a metal-cutting power shear for steel-focused applications on 6-9 ton carriers.
Q: Why choose the rotating model over a fixed shear for tight spaces?
A: The JS80RT functions as a rotating scrap metal rotary shear with 360° continuous rotation (360mm rotation diameter), allowing operators to grab irregular pipes and beams from any angle in narrow corridors and indoor spaces. Fixed models lack this flexibility. The rotating version is ideal for urban demolition where maneuverability is critical.
Q: Will the warranty be shortened under 24-hour continuous operation?
A: The standard 12-month warranty assumes an 8-hour single shift. If your operation runs this mobile scrap shear on a 24-hour schedule, the warranty period is halved. We recommend strict 4-hour lubrication intervals for non-stop urban demolition work to maintain peak performance.
Q: Can the hydraulic shear operate underwater? Is silt damage covered?
A: Prolonged underwater use of this hydraulic shear for excavator is not recommended. If used in wet conditions, immediate full cleaning and greasing are required after each session. Rust or jamming caused by poor maintenance in watery environments is excluded from warranty. An anti-corrosion custom model is available for special applications.
Q: Is damage from improper installation covered by warranty?
A: New 6-9 ton excavators can fit this excavator shear directly via forearm installation, while refit kits are supplied for older machines. Motor or cylinder damage resulting from self-modified oil circuits is excluded from warranty. Standard installation takes only 1–2 hours due to the 580kg lightweight design.
Q: Will insufficient lubrication void the warranty?
A: Grease all pivot points every 4 hours under heavy load, and perform full lubrication after long idle periods. Bearing and pin failures caused by insufficient lubrication on your scrap shear are considered maintenance negligence and are not covered under warranty.
Q: What are the cold-weather operation guidelines?
A: When operating below 0°C, perform a 5–10 minute no-load warm-up before cutting. Use low-temperature hydraulic oil if temperatures drop below -10°C. Cover the machine when stored outdoors. Freeze cracks resulting from poor winter maintenance are excluded from warranty.
Q: Is surface rust from outdoor rain storage covered?
A: A heavy-duty anti-rust coating is applied before delivery of the scrap metal cutting shears. However, surface rust caused by prolonged outdoor storage in the rain without a protective cover is excluded from warranty.
Q: What is the standard storage procedure when the shear is unmounted?
A: Clean all metal slag, coat the Hardox shell with anti-rust oil, fully retract the cylinders, and wrap the unit in waterproof film if stored indoors. Outdoor storage without protection is not recommended.
Q: Are hydraulic leaks and slow movements covered under warranty?
A: Factory defects in valves and cylinders causing leaks or slow movements on the hydraulic demolition shears are covered for 12 months. Damage caused by self-adjusted pressure settings exceeding 200 bar or contaminated hydraulic oil is excluded from warranty.
Q: What voids the 12-month warranty on the slewing bearing and motor?
A: Tooth breakage on the slewing bearing due to insufficient greasing, or motor shaft breakage caused by hard impacts and unauthorized pressure tuning, will void the warranty for these specific components of the excavator scrap metal shear.
Q: What is the lead time for overseas spare parts delivery?
A: Warranty replacement parts are provided free of charge; the buyer bears all freight and tariff costs. Delivery takes 3–7 days from overseas warehouses, 20–40 days by sea, or 7–15 days via air freight for emergency situations.
Q: Can the JS80RT be customized as an OEM unit?
A: Yes. As experienced mobile scrap shear manufacturers, we can customize jaw sizes and hydraulic parameters to meet your OEM requirements. Custom frames still use Hardox450 steel, with a 7–15 day lead time after 3D drawing confirmation. All custom units are engineered specifically for 6-9 ton compact carriers.
Q: What is the export process and payment terms?
A: The MOQ is 1 unit, with bulk discounts available for orders of 10+ sets. We accept T/T, L/C, and Western Union (30% deposit before production). The process is: Confirm Model → Issue PI → Inspection → Shipment.
Q: Do export documents include the Hardox certificate?
A: Yes. Full export documentation includes the Commercial Invoice, B/L, CO, RCEP, CE certificate, official SSAB Hardox certificate, and factory inspection report for smooth global customs clearance.
Q: Is rust occurring during sea transit covered?
A: We use full anti-rust packing with desiccants for every scrap shear unit. Any minor surface oxidation occurring during long sea transit or post-delivery outdoor storage is considered normal and is excluded from warranty.
Q: What is the step-by-step warranty claim process?
A: 1. Provide the serial number of the scrap metal shear, a fault video, and hour records. 2. Our engineers determine if the damage is a factory defect or man-made. 3. Free spare parts and video installation guides are provided for eligible claims. 4. Welding cost reimbursement (200 RMB) applies within 6 months. 5. Cost-price consumables are offered for out-of-warranty needs.
Q: Does mentioning brands like Kubota or CAT imply official cooperation?
A: No. Brand names are mentioned solely to indicate the compatibility of the JS80RT eagle-beak shear with various 6-9 ton carrier models. It does not imply official authorization, endorsement, or trademark infringement by these manufacturers.
